Waterproofing a Bath Step by Step

Waterproofing a Bath Step by Step

Without a good seal on the bath or shower, it can mold in the bathroom because the walls get wet. Careful work is important.

1. Required material for sealing

Wetting of the walls can only be prevented by applying a sealant. For wall corners, additional sealing tape is required and for the joints between the tub and wall silicone. Fittings and drain fittings contain all necessary seals except hemp.

2. These tools are necessary.

Painting can be done with a tassel or a paint roller. For the grout, a caulking gun and silicone trowel are required. The installation of the water connections and the drain is not possible without pipe wrench and belt bowl. Rinsing agent for smoothing the joints is usually in the house anyway.

3. Properly seal the wall

The sealant for the waterproofing must be applied to the wall. The required quantity and the drying time depend on the sealing agent used and can be found in the manufacturer's instructions for use.

4. Carefully treating corners

On wall corners, stress cracks often form, through which water penetrates. This can be prevented with an elastic sealing tape, which is pressed carefully into the still moist sealing coat.

5. Decorative design of the bath area

Water-repellent materials such as tiles and plastic panels are ideal for the immediate area of ​​bathtubs or showers. A coat of water-resistant paint is also possible.

6. Carefully install fittings

When connecting taps, all hoses must be sealed with hemp. Crevices between tiles and pipes disappear under the cuffs, which at the same time protect the area from water. They can be additionally sealed with silicone.

7. Seals on the drain fitting

The set includes a seal that seals the area between the valve and the sump. It has to be assembled carefully, as otherwise water will get under the tub unnoticed.

8. Fill connecting joints with silicone

The gap between the wall and the bath is sealed with a thick, even silicone filling. This gets the perfect shape by peeling off with the joint smoother so that water flows from the wall into the tub and not behind it.

9. Protecting the floor under the bathtub

There is another joint between the bathtub and the floor, through which water gets under the tub. This is also to be sealed with silicone.
